Langston, 1701 W. Berry,Fort Worth, Tex. Filed Feb. 5, 1962, Ser. No. 171,111 Claims. (Cl.68-27) This invention relates to thread dyeing devices and is acontinuation-in-part of my copending application Serial No. 108,637,filed May 8, 196 1.

The primary object of the preset invention is to provide a simplifiedconstruction for selectively dyeing thread different colors.

Another object is to provide a multiple color thread dyeing device whichhas fewer working parts and one which will not require cleaning as oftenas other devices for the same general purpose.

Another object is the provision of a thread tensioner in a multiplecolor thread device, which tensioner is so located and arranged thatuniform feeding of the thread through the device is assured.

A particular object of the invention is to provide a device of thedescribed class including splined coaction between a dye marker and itssupporting member for convenient yet positive action.

These and other objects will become apparent from the followingdescription and accompanying drawing, wherein:

FIGURE 1 is a front elevational View of a multiple color thread dyeingdevice in accordance with the present invention.

FIGURE 2 is a vertical sectional view taken on line 2-2 of FIGURE 1.

FIGURE 3 is a broken perspective view of one end of the base plate.

FIGURE 4 is an inverted broken perspective view of the marker supportingbody.

FIGURE 5 is a broken front elevational View and partly sectional view ofa modified form of the invention.

FIGURE 6 is a vertical sectional view taken on line 6-6 of FIGURE 5, and

FIGURE 7 is a perspective view of one of the markers in accordance withthe modified form of the invention.

The form of the invention shown in FIGURES 1 through 4 includes anelongate rectangular base plate 10 having a similarly shaped body 11mounted thereon. The base plate 10 is designed to be mounted on the headof a shoe repairing sewing machine, not shown, and the body 11 islocated to the left of the operator. Also mounted on the base plate 10,and to the right of the operator, there is a vertical spool pin 12rotatably supporting a spool of thread, and between the spool 13 and thebody 11 there is a thread tensioner, generally designated by the numeral14. The tensioner 14 is comprised of a threaded stud 15 projectingupwardly from the base plate 10, a thumb nut 16 on the upper endthereof, a coiled compression spring 17 around the stud and beneath thethumb nut and a flanged tension disc 18 rotatably mounted on the studand in turning contact with the upper surface of the base plate.

The upper surface of the body 11 is provided with logitudinally alignedbores 19' for slid-ably receiving cylindrical barrels 20, which, inturn, receive commercially available dye markers 21, such as thosemanufactured by Carters Ink Co. The dye markers 21 have tubular bodiesor reservoirs, not numbered, which are functionally received in thebarrels 211. Inwardly directed fianges 22 in the lower ends of thebarrels 20 locate the markers 21 for fully inserting the same in place.Smaller bores 23 in the body 11, and coaxial with the first describedbores 19, receive the marker ferrules 24 and permit the felt tips 25thereof to extend beneath the body 11 when the barrels 20 are in theirlowermost positions. Each barrel 20 has a forwardly extending projection26 for manually raising and lowering the dye markers 21. Verticallydisposed bayonet slots 27 are formed in the forward face of the body 11to accommodate the projections 26.

A longitudinal channel 28 is formed in the upper sur face of the baseplate 20 and has felt pads 29 therein located beneath and to becontacted by the felt tips 25 of the dye markers 21. While the word feltis used herein, it is to be understood that other absorbent resilientmaterial may be used in place thereof, after the pads 29 are in place,the body 11 is secured to the base plate 10 by screws 30 as shown inFIGURE 2.

Thread 31 from the spool 13 is looped about the tension disc 18 andenters the body 11 through an end opening 32 which communicates with alongitudinal groove 33 in the bottom of the body and which grooveconnect-s wiflr opposite sides of the small diameter bores 23. Thethread 31 extends through the groove 33 and outwardly through anotherend opening 34. The thread 31 is then threaded in the sewing machine inthe usual manner.

The modified form of the invention includes the described base plate 10,channel 28 and pads 29 therein, to gether with the described spool pin12 and tensioner 14. However, the body 11a is modified to receivespecial dye markers 35, each consisting of a cylindrical reservoir 36having a relatively thick wall, a screw cap 37 on the upper end, adepending tubular ferrule 38 integral with the lower end thereof and afelt tip or wick 39 extending therethrough. A coiled compression spring40 is mounted around and secured on the upper end of the ferrule 38 andmakes spring contact with the upper surface of the base plate 10 whenthe marker 35 is in its lowered position. As in the first described formof the invention the body 11a includes the longitudinal groove 33 in thebottom surface thereof and openings 32 and 34 in the ends of the bodyfor receiving the thread 31.

Aligned vertical bores 41 extend through body 11a and slidably receivethe lower portions of the markers 35. T-slots 42 are formed in thesurfaces of the cylindrical reservoirs and are engaged by the inner endsof screws 43 mounted in the forward wall of the body 11a.

Both forms of the invention operate in substantially the same way. Bothhave splined coaction between the cylindrical marker reservoirs 21 and36 and their respective supporting bodies 11 and 11a. In the first formof the invention the projection 26 associated with the markor 21containing the selected color is first moved laterally and thendownwardly to cause the felt 25 thereof to contact the thread 31 movingtherebeneath. The weight of the barrel 20 and the marker 21 hold thefelt 25 in place. In the second form of the invention the projectingupper end of the reservoir 35 is pressed downwardly and then rotated tohold the felt 39 against the thread 31. Suitable ca-ps, not shown, maybe placed over the felts 25 and 39 when the device is not used for longperiods of time.

The invention is not limited to the exemplary construction herein shownand described, but may be made in various ways within the scope of theappended claims.
